How to draw a feature on a curved surface on solid works ?
Do I need to draw planes or what ? I want to draw a lofted feature on a curved surface but I cannot draw the feature directly onto the curves. Should I draw it as a part or what? It may be tough to see from the photo but Im trying to draw the pyramidal features. I have no problem drawing them on a flat surface but I cant draw them on the curved surface!!
Thanks for the information and images, now I can help.
I actually made the exact shape couple of days ago.
I can't think of an automated way to do it, either do the curved surface, use Split Line to make the faces then with points for the Lofted Boss feature or as Sudhir suggested.

Draw curved sketch on top plane (6" circle)
Extrude surface 2" or desired amount
Draw sketch "facets" on front plane 1/2"x1/2"
Project curve onto surface
New 3D sketch
Convert Entities "projected curve"
Draw diagonal line between 2 corners
Draw perendicular to diagonal
New plane .(4)
Select line "S" and endpoint of line "S"
New sketch on plane .(4)
Convert Entities endpoint of line "S"
Loft between "facets" on surface and point on plane (4)
Make linear and circular patterns as necessary
To me, the most intuitive way seems to be making perpendicular cuts. I tried it out on a model, and whereas the cuts along the curve swept perfectly, I had some trouble getting the cuts perpendicular to the curve to give me a closed sketch. Let me know if you have trouble figuring out how I made the part.
